Is the Broken Drive Shaft Largely Related to the Driver?
1 Answers
Causes of a broken drive shaft in a car include the dynamic balance of the drive shaft assembly exceeding standard specifications; loose or damaged drive shaft connecting bolts; failure to strictly follow repair process operating procedures during maintenance operations; and improper driving operations that subject the drive shaft to extreme impacts, leading to component damage. Below are the effects and preventive measures for a broken drive shaft: Effects of a Broken Drive Shaft: The drive shaft is a crucial component that transmits power from the transmission to the rear axle. If it breaks or detaches during use, it can easily flip the vehicle, posing severe safety risks. Additionally, clunking noises may occur when starting the car or shifting gears during driving, especially when driving at low speeds in high gears. While there may be no abnormal noise when starting the car, clunking sounds can appear during driving. Preventive Measures for a Broken Drive Shaft: Strictly adhere to technical specifications for regular maintenance to ensure that related components are securely fastened and well-lubricated; rigorously follow repair standards, using a dial indicator on V-blocks to measure drive shaft bending during repairs—correct if it exceeds 0.5mm; promptly replace worn-out universal joints, bearings, and other transmission components; regularly lubricate the center bearing, ensuring the bearing cap is installed with appropriate tightness and adjusting it as needed during use; practice smooth starting and gear shifting, and use the clutch and brakes reasonably to reduce the impact forces generated during power transmission.
